Remote Monitoring for Off-Grid Solutions with Renewable Technologies in Norway
Off-grid households in northern Norway are adopting a mix of renewable technologies to achieve energy independence. This case study explores the challenges, solutions, and experiences of households utilizing solar, wind, biomass, and energy storage systems since 2015. By monitoring solar, wind, temperature, and energy consumption remotely, these off-grid solutions optimize energy production and usage, aiming for near-grid independence while overcoming complex design considerations. The study emphasizes the importance of data monitoring and innovations in enhancing off-grid systems' efficiency and reliability in remote areas.

Case-study concept Background Increasing interest in renewable systems High grid-connection fees in remote areas (>50 000 ) Energy security Grid independence and self-consumption Households in northern part of Norway Started with 1 existing off-grid house, now 4 cases 4 more renewable systems to be investigated Large range of cases; Status installation; from idea to operating Off-grid capability; reducing energy bill, back-up capability, nearly off-grid or functioning off-grid 3/12/2 025 3
Off-grid since 2015 Self sufficient Electricity Heating Water Waste management 3/12/2 025 4
Off-grid since 2015 Numbers 2 kW wind mill ~4 kW solar heating 3,2 kW solar modules Wood furnace with water heating ~12 kW 1000l water accumulator tank 3/12/2 025 5
Challenges Design considerations: Winter months little to no solar energy, need an alternative energy source Overall installations costs and running costs Nearly off-grid costs about the same as standard grid-connection Complexity and uptime Improvements and innovations Lack of data as most systems are not monitored! Experiences from the systems are not widely spread 3/12/2 025 6
Solutions Energy production Energy usage Solar Minimize Wind Selective time of operation Biomass Selective device purchase Energy storage Water accumulation tanks Battery pack Biomass 3/12/2 025 7
Outputs Simulations of systems Estimate production solar and wind Investigate alternative systems and improvements Biomass based Combined Heat and Power systems (CHP) Thermal energy conversion Add-on to existing system Development of standalone data collection system Autonomously operating Ultra-low powered up to 2 years in the field 4G transmission of data Low material costs 3/12/2 025 8
